Bacterial division: Finding the dividing line

Division of a cell - whether eukaryotic or prokaryotic - requires accurate spatial coordination. Recent work on the bacterium Escherichia coli has shown that correct placement of the cell division site at the midcell position occurs by a combination of selection against potential polar sites and selection of the midcell site.

The Structure of the Compton Shifted Line.

their minima, we see at once that the most probable transitions are going to give nuclear separations which will not result in dissociation. This is in perfect accord with experiment. Until we know more of the excited states of the H2+ ion we cannot proceed with explanations of the effects that still faster electrons may produce. 1 Winans and Stueckelberg, these PROCUZDINGS, 14, 867, 1928. 2 We...

Dividing wall columns for heterogeneous azeotropic distillation

The aim of this work is to implement heterogeneous azeotropic distillation schemes in a dividing wall column (DWC) for a feed mixture of water (W), acetic acid (HAC) and an organic component (X). The original design makes use of X to act as an entrainer to facilitate the separation of water and HAC, and we also propose a DWC design based on this idea. This DWC design reduces the capital cost, b...
